新风换气机 meaning in Chinese

freshair exchangerr

There are many kinds of methods dealing with fresh air supplying , such as free fresh air supplying , fresh air sucking , independent fresh air supplying , heat recovery ventilating ( hrv ) , etc . it was proved that ac equipment capability and iaq has a relationship with fresh air states in fan - coiling and fresh air system
除了无组织的新风供应方式，住宅空调系统新风供应还有新风吸入方式、独立新风供应、新风换气机方式。风机盘管加新风系统中，新风处理到不同的状态点，对空调设备负担的负荷及室内空气状态都有影响，本文对各种新风处理状态进行了分析。
It is indicated that hrv has many advantages certified by theoretic analyze and engineering practices , such as fully ventilating , abundant fresh air supplying , energy saving , etc . comparing with independent fresh air supplying , hrv is supposed to cause potential problems , - in summer load of fan - coil units will be increased , and the wet operating mode will be aggravated , the indoor relative humidity will be increased
新风换气机供应新风是住宅空调系统较为理想的新风供应方式，本文通过理论计算及工程实践表明采用，新风换气机具有换气充分、新风量保证、节能等优点。但与新风机组独立供应新风相比，新风换气机供应空调系统新风时，会造成夏季风机盘管负荷增加，湿工况加重，室内相对湿度有增加趋势。
